Creates an XML Document object. This will contain just one empty root element
on which none of the properties will have been set.
The purpose of this call is to allow an application to create
an XML document from scratch without the need to load a
document from a file or string. The document that is created
will be as if a document had been loaded that contained just a single
empty document element with no attributes set or elements within it.

createDocument()
may need to be told what the document element is.
This will not be necessary in simple cases.
When there is no ambiguity then no parameter need be passed to the
method.
However it is possible to load more than one schema file into the same XML DAS
and in this case there may be more than one possible document element defined:
furthermore it is even possible that there are two possible document elements that
differ only in the namespace.
To cope with these cases it is possible to specify either the document element
name, or both the document element name and namespace to the method.

Parameters

document_element_name

The name of the document element. Only needed if there
is more than one possibility.

document_element_namespace_URI

The namespace part of the document element name. Only needed if there is more
than one possible document element with the same name.

dataobject

Return Values

Returns an SDO_XML_DAS_Document object on success.

Errors/Exceptions

SDO_UnsupportedOperationException

Thrown if an element name or element name and namespace URI is passed,
but not found in the underlying model.
